No, contacts generally do not automatically move with a SIM card in modern smartphones; they are usually stored on the phone itself or synced to cloud accounts (like Google or iCloud). You'll need to either use cloud sync, transfer contacts directly from the old phone to the new one, or manually import contacts from a SIM card to the phone's memory if they were saved there.
Most smartphones no longer support storing their contacts on a SIM card. You may, however, transfer contacts from an old SIM card to your phone, provided the old SIM card will fit your phone. Insert your previous SIM card into your phone.
Unfortunately, sim card contacts are not backed up, so these won't be retrievable from your new sim card. However you should be lucky in that Android really doesn't tend to easily allow you to store contacts solely on your sim card (you have to dig around in the settings to do this), so you may find that you are ok.
A SIM contains a unique serial number, integrated circuit card identification (ICCID), international mobile subscriber identity (IMSI) number, security authentication and ciphering information, temporary information related to the local network, a list of the services the user has access to, and four passwords: a ...
Does a SIM card hold contacts? In the past, a SIM card could hold up to 250 contacts. However, most modern phones store your contacts in cloud storage or on the device itself.
And what it does not carry: Photos, apps, messages, or downloads. Your full contact list (unless you've manually saved it to the SIM)
When you insert your SIM card into another phone, you transfer that information to the new device. Your phone number does not change when you transfer phones using your SIM card because your number is linked to the SIM card and the mobile network rather than the specific phone.
Changing sim cards is a fairly easy process. The sim card only holds your phone number's access to the network and none of your information like contacts or apps.
Some SIMs also keep limited contacts and SMS messages, along with temporary network details, while using encryption to protect calls and texts. However, they do not store personal files, photos, apps, or browsing history, those remain on the phone or cloud.
Changing your SIM card will not cause you to lose data that is stored in the cloud or on your device internal storage.
Your old SIM becomes inactive, and your wireless plan, phone number and network connection are all tied to your new SIM. Whether you're changing to a new physical SIM card, or switching to eSIM, the steps usually take just a few minutes and are almost as easy as moving your SIM to another phone.
Under normal usage conditions, you can expect a SIM card to function reliably for approximately 5 to 10 years. However, this lifespan can be significantly shortened by factors like frequent removal and insertion, exposure to moisture, or physical damage.
If you're on Android, you'll typically need to open Contacts app, go into the Settings menu and look for Import or Export Contacts. Then you can move the contacts from your SIM card to your phone. On an iPhone, head into Settings, then choose Contacts and tap Import SIM Contacts.
A SIM card stores essential network information such as your subscriber identity (IMSI), SIM serial number (ICCID), and authentication keys. Some older SIM cards may also hold a small number of contacts or text messages.
In addition to network data, personal information is stored on a SIM card. Things like your phone number, contacts, and text message history are stored on a SIM, which makes it easy to transfer information from one device to another.

The Role of the SIM Card
A SIM card is a small chip that contains your carrier phone settings and provides the link to your phone number. You can change devices and put your SIM card in another phone without losing access to your phone number. The new device would then work using the SIM card.
Your phone number is not permanently linked to your SIM card. Number portability allows you to switch operators or SIM cards while keeping your number. You can change your number without replacing your SIM card by contacting your operator.
To transfer everything to your new phone, charge both devices, connect to Wi-Fi, and use the on-screen setup prompts to copy data wirelessly or with a USB cable from your old phone (Android to Android) by signing into your Google Account and restoring a backup or directly transferring apps, contacts, photos, and settings, with app-specific data like WhatsApp often needing separate in-app backups.
SIM cards contain data including user identity, location, phone number, network authorization, personal security keys, contact lists and stored text messages. They enable a device to be identified and authenticated on the network.
If your current phone won't charge, you can still use your existing SIM card in a new phone. Simply power off the old device, remove the SIM card carefully, and insert it into the new phone's SIM slot. Ensure the new phone is unlocked or compatible with your carrier.
